Is it possible my psoriasis has gone by itself?

I have had psoriasis for years on my right elbow. Super annoying and very persistent, with no regard to exercise, diet, or season. If I didn’t put cream on it, it would flare up really badly. All of a sudden this summer, after close to 10 years, it went away, just like that. I suddenly realized one day that I hadn’t put cream on it in a long time and the area is totally normal – all by itself!

I tried to Google this and read that it’s possible for psoriasis to go into remission, but couldn’t find much else about it. If any of you jellies have experience, would you mind sharing?

Will my psoriasis will flare up again sometime in the future? Should I be concerned that it might pick a different spot to come out, or will it always be the elbow? (I really don’t want it on my head or face)
